Abstract

PURPOSE:To easily and quickly assemble an assembled body, by providing the assembled body by combining numerous plates for transverse row and for longitudinal row in a grid and causing the assembled body to support a male and female plates by putting he male plate on the lower surface of the upper assembled body and the female plate on the lower assembled body. CONSTITUTION:A female die B is installed to the surface plate of a press machine and a male die A is supported by the elevating plate of the press machine. To support the male die A by means of the elevating plate, platy bodies are superposedly put on the upper surface of an assembled body 3 and fixed to a transverse row plates 1 and the elevating plate is caused to support the platy bodies with bolts, etc. Thereafter, a steel plate is pressed against the female die B while the male die A is lowered after the heated steel plate is placed on the female die B and, at the same time, the steel plate is pressed by a male and female plates 4 and 8 so as to form the bent plate at the mouthpiece section.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a mold for manufacturing large products such as dam discharge pipes, branch pipes, sand discharge pipes, and mouths of discharge pipes from steel plates. .

[Conventional technology]

In a mold for producing a large product, for example, in the case of a spout, a peripheral wall is formed by sequentially adding a large number of bent molded plates.

Further, since the shape and dimensions of the above-mentioned drinking spout vary each time, a mold for a bent plate is manufactured for each order.

The upper C mold has a large number of parallel plates having arcuate edges along the bending line of the bending molded plate on the lower edge, and the edge of each column plate is fixed to the end plate by welding. A large number of horizontal plates (arranged to withstand the strength during pressing) are fitted with a predetermined interval between the vertical plates, and the side edges of the horizontal plates are fixed to the vertical plates by welding to form a lattice. After that, a male plate for single-sided molding of the bending forming plate is superimposed on the 'F side of the above assembly, and it is fixed to the longitudinal plate and the end plate by welding to form a male mold. .

In addition, a large number of vertical plates each having an arc-shaped recessed edge along the bending line of the bent molded plate are arranged in parallel on the upper edge, and the edges of the vertical plates are fixed to the end plate by welding, and then the vertical plates are interposed between the vertical plates. A large number of horizontal plates (arranged so as to withstand the strength during pressing) are fitted at predetermined intervals, and the side edges of the horizontal plates are fixed to the vertical plates by welding to form a lattice-like assembly. After that, a female plate for single-sided molding with the remaining bending molded plate is stacked on the upper surface of the above assembly, and the female mold is made by welding to the vertical plate and the end plate.

[Problem 3 to be solved by the invention: When producing a set of books, a large number of row plates are fixed to the column plates by welding, which requires a lot of work to weld and cannot be easily disassembled, making it difficult to re-assemble the column and row plates. Since it could not be used and was disposed of as scrap, there was a problem that caused the mold to rise.

Furthermore, since a new mold is manufactured in response to an order, there is also the problem that a long period of time is required between receiving the order and delivery.

[Means for Solving the Problems] In order to solve the above problems, the present invention includes a large number of parallel row plates and vertical plates each having an arc-shaped ridge along the bending line of the bending molded plate at the lower edge. A male mold consisting of an assembly assembled in a lattice shape by inserting slits provided in each from the top and bottom directions, and a male plate for single-sided molding of a bending molding plate supported by stacking on the r side of this assembly. and an assembly in which a large number of parallel row plates and column plates each having an arc-shaped recessed edge along the bending line of the bent molded plate on the upper edge are assembled into a lattice shape by inserting slits provided in each plate from above and below. , and a female mold made up of a bending molding plate superimposed and supported on the upper surface of the assembly and a female plate for single-sided molding.

[Effect]

The female die is installed on the surface plate of the press machine, and the male plate is supported by the lifting plate of the 177 machine.

Next, after placing the heated steel plate on the female mold, the male plate is lowered together with the lifting plate to press the steel plate against the female mold, and the steel plate is sandwiched between the female plate and the male plate to produce a bending molded plate. do.

〔Example〕

In the figure, A is the male type.

The above male type A has a large number of parallel row plates 1 and column plates 2 each having an arcuate protrusion along the bending line of the bent molded plate at the lower edge. It is composed of an assembly 3 which is assembled into a lattice shape by inserting the assembly 3 into the assembly 3, and a male plate 4 for single-sided molding of a bending molding plate which is stacked and supported on the lower surface of the assembly 3.

B is female.

The female mold B described above has a large number of parallel row plates 5 and vertical plates 6 each having an arcuate ridge along the bending line of the bent molded plate on the upper edge, each having slits 5' and 6'e in the vertical direction. It is composed of an assembly 7 which is assembled into a lattice shape by inserting the assembly 7 into the assembly 7, and a female plate 8 for single-sided molding, which is a bent molding plate that is stacked and supported on the upper surface of the assembly 7.

In order to support the male plate 4 and female plate 8 with respect to the above-mentioned assemblies 3 and 7, protrusions 1o having through holes 9 are provided at appropriate positions on the upper surface of the male plate 4 and the lower surface of the female plate 8 in the illustrated case. 5, column, provisional 2, 6
A through hole 11 was provided to match the through hole 9, and both feed holes 9, 1 and 1 vc pins 12 were inserted therethrough.
The male plate 4 and female plate 8 may be partially fixed to the assemblies 3 and 7 by welding so that they can be easily removed.

Further, as shown in the figure, a through hole 13 is provided at both ends of the upper edge of each row plate 1 of the male type A, and a rod 15 having a stopper 14 is passed through the end of the through hole 13, and the rod 1! : By screwing the nut plate 16 into the tip of i, it is possible to prevent the row plate 1 from falling off during handling.

Next, how to use it will be explained.

The female die is installed on the surface plate of the press machine, and the male die is supported on the lift plate of the press machine (this method of support involves stacking the plate-like bodies on the top of the assembly 3, fixing them to the row plates, and then supporting the lift plate on the lift plate). (by fastening the plate-like body with bolts, etc.).

After placing the heated steel plate on the female die B, the steel plate is pressed onto the female die B while the male die A is lowered, and the steel plate is pinched between the male plate 4 and the female plate 8. As shown in the figure, the bent portion C of the spout is molded.

〔effect〕

As described above, according to the mold according to the present invention, an assembly is provided by combining a large number of horizontal plates and vertical plates in a lattice shape by fitting the slits from above and below, and a male plate is provided on the lower surface of the upper assembly. Since the female plates are stacked on top of the lower assembly and supported by the assembly, it takes time and effort to drop the row plates between the column plates and then fix the row plates to the column plates by welding. No work is required, and the assembly can be assembled extremely easily and quickly.

In addition, the assembly can be easily and quickly disassembled by removing the male and female plates from the assembly, so the protruding edges and recessed edges of the row and column plates can be processed and reused. As a result, the unit price of the mold becomes cheaper.
